This is a problem that seems to have existed since I started using /e/OS and Murena (i.e., many years ago). I almost have come to accept that I can’t expect anything from Murena Cloud, but sometimes it’s annoying, especially when my phone shows me notifications that “my cloud space is almost full” even though I cleaned it up a long time ago.
It seems that Murena Cloud only syncs with the files on my smartphone “once in a while”. Today I took a quick look at the Murena Cloud web interface and saw that the last synchronizations of folders in which I added images a few days ago… date back several months (so the images aren’t there, but I do find images that I deleted a long time ago). And for some (sub)folders, seemingly at random, Murena decides to synchronize them, and then I can see recent changes that are correctly replicated. However, I use the “sync” button on the /e/os interface on my smartphone, but it seems to completely ignore it. Is there an explanation for this erratic behavior? Any possible solutions?
